, The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concerne Be it knowsl that I, WILLIAM HUFFMAN, of the city of Oshkosh, State of Wisconsin,.have invented a new and improved Paddle-vllieel for propelling vessels on water; and l: do hereby declare that' the following is a full and exact description thereof, reference being had to the accompanying drawings, and to tl:e letters of reference marked thereon, making a part ol' this specification.

The nature of my invention consists in providingr a paddlewheel w h flanges, and a lining, and with floats, coustructfi on the helical system.V The floats, with tl1'e,lang,es,at suitableA intervals, are provided duplex, right aridle't, the inclinatonslof i the helices' beingy in a contrary direction.

To enable others'skilled in the art to make and use tion and operation. t i

The wheels are provided with radial arms, collars,

and shafts, of any known form. V

Fgure4 is a vertical section, cutting through the dotted line d d, iig. 3. i

tl'lhe airowsindicate the paddle-wheelsy The'wheels describedare more particularly for. use

fbrward movement of the The duplex Heat, shown in fig. 5, is ilnzuse more particnlarly in stern-wheels, the two wheels described be. ing practically consolidated into'one for that purpose, the general construction o f the wheel beingtlie same The duplex' float lnay also, option, be used in iide-wheeltvessels. 4

Each of't le loats c is provided with aigspassages, l'

c, and with flanges e' c', seen in figs. 2 and 6, to check the passage of water through the air-passages.

In the flanges a a, at the bottom, and between each float, are air-passages, e, and tlangese', shown in figs.

3 and 4.

'I will now proceed to describe the operation of my peddlvhssls c.

The arrangement 'bf/the righi; and left wheels, with a succession ot', helica/oats, on a side-wheel vessel, coming in contact W th thewater, each iloat cominencing at one side o the wheel, crossing over tothe.

other side, and only relaxes its hold nu thewater as the following llo'at shall have come well intofcornpensating service. Hence, tlie pressure `on the water is continuous and unifor and vessels propelled b vniy paddle-wheel are free f om vibration.

The addition of the lianges and lining to the heats,

" in combination .with the.- heical setting, the air-pas'- sages permitting a free discharge ofthe water from the bucket, give's my paddle-wheel a `more tenacious hold ou the water, and in combination with the water 'being discharged toward the boat, the boat sits more buoyantly on the water, draws less water, and the boat y i is propelled more easily.

`In turning the boat any given direction, reverse the inside wheel, the opposite wheel retaining a njwanl motion, the water will be cast away from the boat, on the inside, and toward the boat ou the outside, the boat will be canted, and the preponderance of weight will be toward the inside vof the-circle described in turning, and the boat will be more easilyaud speedily4 turned.

What'I claim as my invention, and desire to ,sec-ure by Letters Patent, is- I 1. Duplex helical lloats, fig.` 5, in combi-nation witl lining?) and flanges a, a., provided with nir-passages r e, in either flanges or lioats, or both.

2. The air-passages e e, provided with flanges e' c', in combination with paddle-wheels, substantiallyns 'and for the purposes setforth. f c
